IOMMU/DT folks, any thoughts about this approach? The patches that are
of interest outside of Host1x/TegraDRM specifics are patches 1, 2, 4,
and 5.
FWIW it looks fairly innocuous to me. I don't understand host1x -
neither hardware nor driver abstractions - well enough to meaningfully
review it all (e.g. maybe it's deliberate that the bus .dma_configure
method isn't used?), but the SMMU patch seems fine given the Kconfig
solution to avoid module linkage problems.
Thanks Robin! Will, Joerg, is OK with you?
Mikko, I believe we are missing a dt-binding change to document the
'memory-contexts' node which I assume you will add if everyone is OK
with this?
Cheers
Jon
